here's the same graph, with one more curve added: the result of Pretzel_Logic.wav(played in foobar, output = Primary Sound Driver)-->recorded with Total Recorder (48kHz/16bit,w hich is the native format of this setup)-->trim to match the audio segment (audition)--->convert to 44.1kHz(audition) --> replaygain scan with Foobar--->frequency profile scan with Audition-->graph (with RPG adjusted levels)

This is basically a test to see how foobar2k behaves with my work system (which is not set to output digital audio, and which outputs audio at 48kHz) compared to what sabreghagen got. The result is the blue line.
